ELI5: Explain Like I'm 5

House Energy Rating

House energy rating is like a score that we use to measure how energy efficient a house is. Just like in school, where you get a score from A+ to F, a house also gets a rating from A+ to G. To get a good score, your house needs to use energy efficiently, which means having energy-efficient appliances, good insulation and keeping your house cool in the summer by closing the curtains and windows during the day. The better your house scores, the more money you'll save on electricity bills and the more eco-friendly your house will be.
